TC HeliconCRITICAL MASS Vocal Effects Pedal

Independent shopping perspective
The Korena take
Critical Mass puts vocal reverb, doubling, harmony, distortion, and tone shaping in a foot-operated pedal. Hall and Room choices add vocal space, while doubling blends a pitch-shifted second vocal beneath the original; distortion adds grit. Its stompbox interface lets you change effects in real time, and one-touch harmony access provides four melodic and four gang-style presets. Connect a microphone and call up effects or group-vocal treatments at your feet during a performance.
Strong match
Who this is for
- Live vocal passages that need effects changes by foot while the performance continues.
- Live songs needing selectable melodic harmonies or more energetic gang-style vocal parts on demand.
Consider the trade-offs
When to look elsewhere
- Vocal setups that need a harmony choice beyond four melodic and four gang-style presets.
